125 GeV Higgs boson and the type-II seesaw model

TL;DR: In this article, the authors studied the stability and unitarity conditions for a 125 GeV Standard Model-like Higgs boson mass in the type-II seesaw model, and showed that, as long as the seesaw scale is introduced below the SM vacuum instability bound, there exists a large parameter space predicting a 125 geV Higgs mass, irrespective of the exact value of the sawaw scale.
Journal ArticleDOI

Almost no scale supergravity

TL;DR: In this paper, a 5-dimensional supergravity model is presented, where the radion is stabilized by Casimir energy from supergravity and massive hypermultiplets, and all moduli are stabilized consistently by low-energy dynamics in the effective theory.

125 GeV Higgs Boson Mass and Muon g−2 in 5D MSSM

TL;DR: In this article, a 5D framework of the minimal supersymmetric standard model with the Randall-Sundrum warped background metric is considered, and a mass hierarchy is achieved in terms of geometry.
Journal ArticleDOI

Vacuum stability and naturalness in type-II seesaw

TL;DR: In this paper, the authors studied the vacuum stability and perturbativity conditions in the minimal type-II seesaw model, and they showed that the branching ratios of the Higgs decay deviate from the standard model, due to the effects of the triplet scalar field.
